Bearing sealing cover for heavy roller

Abstract

The invention provides a bearing sealing cover for a heavy roller, and relates to the technical field of roller structures of roller conveyors. The bearing sealing cover has good sealing property and strong reliability, and ensures flexibility and service life of a bearing. The technical scheme is that: the bearing sealing cover comprises a steel pipe, a bearing, a shaft and a plastic cover, wherein the plastic cover is pressed on the outer end face of the bearing; the outer edge of the plastic cover is pressed on a convergent inner wall of the steel pipe; and the inner edge of the plastic cover is attached to the outer circular surface of the shaft. The bearing sealing cover for the heavy roller is characterized in that the plastic cover comprises an inner cover and an outer cover, wherein the inner end face of the outer cover is embedded in the outer end face of the inner cover.

Description

technical field [0001] The invention relates to the technical field of the roller structure of a roller conveyor, in particular to a bearing seal cover of a heavy roller. Background technique [0002] Heavy-duty rollers are mainly used on mine conveyors, where the working environment is relatively harsh, and the requirements for dustproof and waterproof sealing are high. For the dustproof and waterproof structure of the existing heavy-duty drum, see figure 1 , it installs a plastic cover 2 on the outer end surface of the bearing 1, the outer edge of the plastic cover 2 is press-fitted on the closing surface of the steel pipe 3, and the inner edge of the plastic cover 2 fits the outer circular surface of the shaft 4. The disadvantages are: : With the long-term rotation of the heavy-duty roller, the plastic dust cover is easy to move outward, exposing the gap, and dust, water and other sundries are easy to enter the bearing, which affects the flexibility and life of the r...
